S2SH web.xml 同时配置Struts2与Servlet的解决方法

一、两种网上的方法，本人是想在说s2sh项目中加入xheditor（在线编辑器）功能，通过下面的两种方法发现不是action有问题，就是servlet有问题，因此不行。

但是毕竟这两种方法简单好理解，不放先试一下，说不定你的项目能行。

解决Could notfind action or result There is noAction mapped for namespace / and action nameChk有两种偏门的办法：1、修改servlet的配置文件的<url-pattern>,struts2的filter中<url-pattern>不变2、修改struts2的filter中<url-pattern>，servlet中的<url-pattern>不变

原配置文件：
<filter>

<filter-name>struts2</filter-name>

<filter-class>

org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter

</filter-class>

</filter>
<filter-mapping>

<filter-name>struts2</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>
<servlet>

<servlet-name>Chk</servlet-name>

<servlet-class>com.thdx.action.Chk</servlet-class>

</servlet>
<servlet-mapping>

<servlet-name>Chk</servlet-name>

<url-pattern>/Chk</url-pattern>

</servlet-mapping>
修改后
.........
<filter-name>struts2</filter-name>

<url-pattern>*.action</url-pattern>

</filter-mapping> //servlet中的<url-pattern>不变
或
.....
<servlet-mapping>

<servlet-name>Chk</servlet-name>

<url-pattern>/Chk.servlet</url-pattern>//点后面随便怎么写

</servlet-mapping> //struts2的filter中<url-pattern>不变

二、一种保证有效的方法

package com.xheditor.servlet;

import java.io.IOException;

import java.util.ArrayList;

import java.util.Arrays;

import javax.servlet.Filter;

import javax.servlet.FilterChain;

import javax.servlet.FilterConfig;

import javax.servlet.RequestDispatcher;

import javax.servlet.ServletException;

import javax.servlet.ServletRequest;

import javax.servlet.ServletResponse;

import javax.servlet.http.HttpServletRequest;

/**

* 该类是定义了一个过滤器（随便你放在摸个包下面），当既用到struts2有用到servlet时，

* 必须用该过滤器对所有的servlet做一次过滤，否则servlet将无法正常运行。

* 同时在web.xml中，在定义struts的核心控制器前面添加该过滤器，添加代码如下：

* <filter>

* <filter-name>redisp</filter-name>

* <filter-class>filters.ReDispatcherFilter（该过滤器的类名）</filter-class>

* <init-param>

* <param-name>includeServlets</param-name>

* <param-value>所配置的servlet，注意是那url-pattern</param-value>

* </init-param>

* </filter>

* <filter-mapping>

* <filter-name>redisp</filter-name>

* <url-pattern>/*</url-pattern>

* </filter-mapping>

* @author xsl

*

*/

public class ReDispatcherFilter implements Filter {

public void destroy() {

// TODO Auto-generated method stub

}

public void doFilter(ServletRequest req, ServletResponse resp,

FilterChain chain) throws IOException, ServletException

{

HttpServletRequest request = (HttpServletRequest)req;

String target = request.getRequestURI();

target = target.lastIndexOf("?")>0

?target.substring(target.lastIndexOf("/")+1,target.lastIndexOf("?")-target.lastIndexOf("/"))

:target.substring(target.lastIndexOf("/")+1);

System.out.println(target);

if(this.includes.contains(target))

{

RequestDispatcher rdsp = request.getRequestDispatcher(target);

System.out.println("go..............."+rdsp);

rdsp.forward(req, resp);

}

else

chain.doFilter(req, resp);

}

private ArrayList<String> includes = new ArrayList<String>();

public void init(FilterConfig config) throws ServletException {

this.includes.addAll( Arrays.asList(config.getInitParameter("includeServlets").split(",")));

}

}

怕大家还是配置错误，给一个web.xml的配置实例。

<filter>

<filter-name>redisp</filter-name>

<filter-class>com.xheditor.servlet.ReDispatcherFilter</filter-class>

<init-param>

<param-name>includeServlets</param-name>

<param-value>UploadFileServlet</param-value>

</init-param>

</filter>

<filter-mapping>

<filter-name>redisp</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

<filter>

<filter-name>struts2</filter-name>

<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>

</filter>

<filter-mapping>

<filter-name>struts2</filter-name>

<url-pattern>/*</url-pattern>

</filter-mapping>

<servlet>

<servlet-name>XhEditor</servlet-name>

<servlet-class>com.xheditor.servlet.UploadFileServlet</servlet-class>

</servlet>

<servlet-mapping>

<servlet-name>XhEditor</servlet-name>

<url-pattern>/UploadFileServlet</url-pattern>

</servlet-mapping>
